Hi I am considering purchasing a Canon t3i and would like to know if anyone has read any books for dummies type of book for helping me learn the basics and some good tips quickly before I go to the Peruvian Amazon and Machu Picchu.

Which lenses are recommended for wildlife and landscapes?

I also need a good bag. My husband has a nikon d80 with a bag with one shoulder strap and its tough on the shoulder after a long day of hiking through the jungle.

For wildlife, the 55-250mm lens offers a good amount of bang for your buck but if you're looking for more a bit more reach and sharpness and your budget permits, there are the 70-300mm offerings from Canon and Tamron to consider.

For landscapes Tokina's 11-16mm is sharp even at f/2.8 though it is pretty pricey, in which case Canon's 10-22mm is very good too.

I realize it may exceed your budget, but considering the amount of rainfall in the Peruvian Amazon, I would strongly recommend a weather sealed camera like the Canon 7D. Sure the T3i may be cheaper in the short run, but what happens if you have to replace it?
